Isoke is solving the quadratic equation by completing the square.
10x2 + 40x – 13 = 0
10x2 + 40x = 13
a(x2 + 4x) = 13
what is the value of a?

Step-by-step explanation:

10 is the value of A

Value of A = 10

Step-by-step explanation:

Here Isoke is solving the quadratic equation by completing the square

        10x² + 40x – 13 = 0

         10x² + 40x – 13 + 13 = 0 + 13

         10x² + 40x + 0 = 13

         10x² + 40x = 13

          10 ( x² + 4x) = 13

   Here it is given as

           A(x² + 4x) = 13  

Comparing both

           We will get A = 10

Value of A = 10

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

answer: 88
